How to Detect and Block UltraSurf program traffic

hi
you know after my successful experiment to block Hotspot Shield , we have tried other different types of programs to bypass network policy and one of the most fastest program is UltraSurf
[www.ultrareach.com]
you know it is more faster than Hotspot Shield and it does not need to be installed and you can download it in EXE file , you just need double click on it and run it
but it is more sophisticated in the way it operate and the way it get their proxy server ip addresses

""Ultrasurf sets up a local proxy on the user’s computer, and then configures Internet
Explorer’s proxy settings to run all Internet requests through that local proxy. It works
automatically with Internet Explorer; however, the user can also use Firefox or any other
browser that supports a proxy configuration by manually changing the browser’s proxy
settings. The default port is 9666

The user can then browse any Internet site normally using IE. All traffic funnels through
the local Ultrasurf proxy. Since the traffic between Ultrasurf and IE is entirely on the
localhost, it never goes to the network and can’t be blocked by a network device.

Ultrasurf then sets up an encrypted connection with a remote server in its network of
proxy servers

The connection to the remote proxy server is made over port 443, which is the standard
HTTPS port

UltraSurf can discover its proxy servers by the following ways
1-A cache file of proxy server IPs stored in the user’s local temp directory from a previous execution
2-DNS requests to external DNS servers, which return encoded IPs of proxy servers.
3-A document on Google Docs containing a rapidly updated, signed and encrypted list of active proxy servers
4- static list of proxy server IPs built into the program
5-Once Ultrasurf discovers a proxy server in its network, it can retrieve IP addresses of other proxy servers directly from that server """ copied

by using the last link i tried to capture packet coming from UltraSurf using wireshark on port 443
to see which server they are connecting to on port 443
i found three major servers with the following range
204.107.140.0/24 , 65.49.0.0/17, 72.0.0.0/8
so i made an address-list and added these address to them

then using these address list we can match on users who are trying to connecting to these proxy servers on 443
and so we can catch all the traffic that is coming from UltraSurfUsers and add its destinations to an address-list named with UltraSurfProxies
